Arteries Gastrocnemius

The gastrocnemius artery is a large artery in the leg that runs through the leg and foot and supplies blood to these areas. The gastrocnemius artery can be divided into three main sections: anterior, posterior and plantar.

Anterior section of the gastrocnemius artery - a. tibialis anterior - is a continuation of the deep femoral artery, starting at the medial condyle of the femur. Below the knee, the artery passes across the anterior surface of the leg and exits under the fascia lata on the lateral side of the quadriceps tendon. Near the knees, the artery ascends in the fascia of the leg, passing along the edge of the fibula to the front of the ankle joint. After which it continues along the lateral edge of the tibia and passes to the foot in its lower third.

The posterior and proximal section of the sural artery - a, tibia profunda - is a continuation of the external iliac artery, originating from the anterior edge of the superior branch of the ischium. Passing along the medial side of the leg, the artery occupies a subfascial position and hides in the lateral fascia of the foot, located behind the medial muscle groups. Its terminal sections are the popliteal and anterior tibial arteries. The popliteal artery is located outside the choroid of the leg, in the popliteal fossa, then rises up to the knee, and, expanding, forms the anterior tibial artery and goes into the foot. The anterior tibial artery runs toward the foot along the lateral side of the front of the leg. With the help of the plantar and dorsal arteries of the leg, it anastomoses with other branches of the sural arteries and the superficial femoral artery to provide blood flow to the foot. In addition, the tibia profunda is one of the components of the basis for the formation of the main lymphatic pathway of the leg - the deep lymphatic system of the leg. The plantar section of the calf artery - a calcanea - is a continuation of the middle section of the posterior tibial arteries, located in the posterior metatarsal region under the fascia of the sole of the foot. The artery begins on the posteromedial edge of the calcaneus and passes into the back of the heel without giving off any branches. Continuing its movement, it anasthetizes with the arteries of the foot and is responsible for blood flow in this area.
